Photon path

  1. Sep 14, 2010 #1
    has any one ever measured the path an electron take through space is it a straight light or is there an unknown interference that moves a photon in a wave pattern?

    Photon is not a point particle and can't be such. Therefore certainly it will not move along a "straight line". Moreover, when you try to observe a moving particle (like an electron) - you disturb it, so again do not expect it to be "moving along a straight line".
    But electron tracks observed in cloud chambers show an "approximately straight pattern" in the absence of external fields.

    Would a photon moving in a vacuum with no external fields presents move in a ''curved'' pattern following is wave pattern?
